Abstract
We analyzed the incidence and predictors of symptomatic repeat Neisseria gonorrhoeae (NG) infection among men who have sex with men (MSM) enrolled in the Bangkok MSM Cohort Study. Thai MSM aged ≥18 years were enrolled during 2006–2010 and followed every four months. At baseline, participants were screened for rectal and urethral NG and Chlamydia trachomatis (CT) infections using nucleic acid amplification testing (NAAT), rectal and pharyngeal NG by culture, and pharyngeal CT by NAAT. During follow-up, symptomatic participants were tested for NG infection by NAAT and Gram stain of rectal or urethral specimens. Among 1464 participants without NG infection at the baseline visit and having at least one follow-up visit, 11.2% (164/1464) developed symptomatic NG infection, for a total of 251 infections. Symptomatic repeat NG infection occurred in 28.0% (46/164) of participants. The incidence rate was 3.9 cases per 100 person-years. Baseline predictors of repeat symptomatic NG were as follows: unknown human immunodeficiency virus (HIV) status despite history of HIV testing, previous sexually transmitted infection diagnosis by physician, insertive-only anal intercourse without a condom, amyl nitrate use at baseline, CT infection at baseline, age 18–24 years, and being a student; HIV infection at baseline or during the study period was also associated with repeat symptomatic NG infection.

Abstract
OBJECTIVES Over the last 15 years, the prevalence of HIV in Haiti has stabilised to around 2.0%. However, key populations remain at higher risk of contracting HIV and other sexually transmitted infections (STIs). The prevalence of HIV is 12.9% among men having sex with men (MSM). There is limited information about the prevalence of other STI in the Haitian population in general and even less among key populations. We assessed the burden of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) and risk factors for infections among MSM in Haiti. METHODS A cross-sectional study was conducted. MSM were recruited from seven health facilities in Port-au-Prince. All samples were tested by nucleic acid amplification test, using GeneXpert. A survey was administered to the participants to collect socio-demographic, clinical and risk behaviour data. RESULTS A total of 216 MSM were recruited in the study. The prevalence rates of CT and NG were 11.1% and 16.2%, respectively. CT NG co-infections were found in 10/216 (4.6%) of the participants. There were 39 MSM with rectal STI compared with 17 with genital infections. Participants between 18-24 and 30-34 years old were significantly more likely to be infected with NG than those aged 35 years or older (OR: 22.96, 95% CI: 2.79 to 188.5; OR: 15.1, 95% CI: 1.68 to 135.4, respectively). Participants who never attended school or had some primary education were significantly more likely to be infected with NG than those with secondary education or higher (OR: 3.38, 95% CI: 1.26 to 9.07). People tested negative for HIV were significantly more likely to be infected with CT than people living with HIV/AIDS (OR: 3.91, 95% CI: 1.37 to 11.2). CONCLUSIONS Periodic risk assessment and testing for STI should be offered in Haiti as part of a comprehensive strategy to improve the sexual health of key populations.

Comparison of an in-house real-time duplex PCR assay with commercial HOLOGIC® APTIMA assays for the detection of Neisseria gonorrhoeae and Chlamydia trachomatis in urine and extra-genital specimens. BMC Infect Dis 2019; 19:6. [PMID: 30606127 PMCID: PMC6318993 DOI: 10.1186/s12879-018-3629-0] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2018] [Accepted: 12/18/2018] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Extra-genital Neisseria gonorrhoeae and Chlamydia trachomatis infections are mostly asymptomatic, and important reservoir sites of infection as they often go undetected and may be more difficult to eradicate with recommended therapeutic regimens. Commercial nucleic acid amplification tests (NAATs) have not received regulatory approval for the detection of N. gonorrhoeae and C. trachomatis in extra-genital specimens. The HOLOGIC® APTIMA Combo2 assay for N. gonorrhoeae and C. trachomatis has performed well in evaluations using extra-genital specimens. METHODS We assessed the performance of an in-house real-time duplex PCR assay for the detection of N. gonorrhoeae and C. trachomatis in urine and extra-genital specimens using the HOLOGIC® APTIMA assays as gold standard comparators. Urine, oropharyngeal and ano-rectal specimens were collected from each of 200 men-who-have-sex-with-men (MSM) between December 2011 and July 2012. RESULTS For N. gonorrhoeae detection, the in-house PCR assay showed 98.5-100% correlation agreement with the APTIMA assays, depending on specimen type. Sensitivity for N. gonorrhoeae detection was 82.4% for ano-rectal specimens, 83.3% for oropharyngeal specimens, and 85.7% for urine; and specificity was 100% with all specimen types. The positive predictive value (PPV) for N. gonorrhoeae detection was 100% and the negative predictive value (NPV) varied with sample type, ranging from 98.5-99.5%. For C. trachomatis detection, correlation between the assays was 100% for all specimen types. The sensitivity, specificity, PPV and NPV of the in-house PCR assay was 100% for C. trachomatis detection, irrespective of specimen type. CONCLUSION The in-house duplex real-time PCR assay showed acceptable performance characteristics in comparison with the APTIMA® assays for the detection of extra-genital N. gonorrhoeae and C. trachomatis.

Abstract
OBJECTIVE To investigate the trends in the incidence of gonorrhoea through an extended period of time and to compare the epidemiology of gonorrhoea infection between 2 distinct ethnic groups (Jews and Arabs). DESIGN A retrospective population-based cohort study was conducted on all consecutive patients diagnosed with gonorrhoea through the years 2001-2015. SETTING National Department of Epidemiology of the Ministry of Health, Haifa District, Israel. PARTICIPANTS A total of 837 reports on gonorrhoea were received, derived from 779 (93.1%) male and 58 (6.9%) female patients. Approximately 1 million people reside in the Haifa region. PRIMARY AND SECONDARY OUTCOME MEASURES We examined the incidence rate of gonorrhoea among residents of Haifa District, northern Israel from 2001 to 2015, by reviewing archives of the Department of Epidemiology, Israeli Ministry of Health. Notified cases were stratified by age, gender and ethnicity. RESULTS The overall gonorrhoea incidence was 6.4 cases per 100 000 population per year. The annual incidence rate dropped from 20.5 per 100 000 population in 2001 to a period of 2.2 cases per 100 000 population in 2005, showing a >9-fold decline. This was followed by a relatively steady increase of incidence of 2.5-4.5 per 100 000 population from 2006 to 2015. Men were predominantly more affected than women, with a 13.4-fold higher incidence rate. The most affected age group was residents between 25 and 34 years old. The estimated rate among Jews was 2.5-fold higher relative to Arabs. Only 1.3% recurrent episodes of gonorrhoea were reported. The prevalence of HIV positivity among patients with gonorrhoea is significantly higher than that of the general population (500.0 vs 88.1 cases per 100 000 population, respectively, p<0.001). CONCLUSIONS Gonorrhoea incidence rate decreased dramatically until 2005, with no substantial subsequent fluctuations. The infection is much more prevalent among patients of Jewish ethnicity, possibly due to riskier sex practices.

Abstract
OBJECTIVE The sexual transmission of enteric diseases poses an important public health challenge. We aimed to build a prediction model capable of identifying individuals with a reported enteric disease who could be at risk of acquiring future sexually transmitted infections (STIs). MATERIALS AND METHODS Passive surveillance data on Montreal residents with at least 1 enteric disease report was used to construct the prediction model. Cases were defined as all subjects with at least 1 STI report following their initial enteric disease episode. A final logistic regression prediction model was chosen using forward stepwise selection. RESULTS The prediction model with the greatest validity included age, sex, residential location, number of STI episodes experienced prior to the first enteric disease episode, type of enteric disease acquired, and an interaction term between age and male sex. This model had an area under the curve of 0.77 and had acceptable calibration. DISCUSSION A coordinated public health response to the sexual transmission of enteric diseases requires that a distinction be made between cases of enteric diseases transmitted through sexual activity from those transmitted through contaminated food or water. A prediction model can aid public health officials in identifying individuals who may have a higher risk of sexually acquiring a reportable disease. Once identified, these individuals could receive specialized intervention to prevent future infection. CONCLUSION The information produced from a prediction model capable of identifying higher risk individuals can be used to guide efforts in investigating and controlling reported cases of enteric diseases and STIs.

Abstract
OBJECTIVES Studies of public health reporting have only examined multiple episodes of the same communicable disease within an individual. We aimed to characterize Montreal residents with multiple reportable disease episodes from 1990 to 2012, while accounting for all types of reportable diseases. STUDY DESIGN Retrospective cohort study. METHODS We performed an exploratory analysis using descriptive statistics, contingency tables, and logistic regression. RESULTS There were 157,839 individuals with at least one disease report and a total of 179,455 disease reports. The 9.8% of subjects with more than one episode accounted for 20.7% of all reported episodes. Among subjects with four or fewer episodes, 54.0% were women, while 74.3% of subjects with five or more episodes were men. Subjects with multiple episodes were more likely to be reported for sexually transmitted infections than were persons with a single episode [difference of proportions: 10.4% (95% CI: 10.0%-10.9%)] and to reside in the neighbourhood encompassing Montreal's gay village. CONCLUSIONS Individuals with multiple communicable disease reports place a large burden on public health officials. These results may help guide investigation and prevention efforts to reduce the number of excess episodes.

Abstract
BACKGROUND Centers for Disease Control and Prevention guidelines recommend azithromycin or doxycycline for treatment of rectal chlamydial infection. METHODS We created a retrospective cohort of male patients diagnosed as having rectal chlamydia between 1993 and 2012 at a sexually transmitted disease clinic in Seattle, Washington. Men were included in the analysis if they were treated with azithromycin (1 g single dose) or doxycycline (100 mg twice a day × 7 days) within 60 days of chlamydia diagnosis and returned for repeat testing 14 to 180 days after treatment. We compared the risk of persistent/recurrent rectal chlamydial infection among recipients of the 2 drug regimens using 4 follow-up testing time intervals (14-30, 60, 90, and 180 days). RESULTS Of 1835 cases of rectal chlamydia diagnosed in the study period, 1480 (81%) were treated with azithromycin or doxycycline without a second drug active against Chlamydia trachomatis. Of these, 407 (33%) of 1231 azithromycin-treated men and 95 (38%) of 249 doxycycline-treated men were retested 14 to 180 days after treatment (P = 0.12); 88 (22%) and 8 (8%), respectively, had persistent/recurrent infection (P = 0.002). Persistent/recurrent infection was higher among men treated with azithromycin compared with doxycycline at 14 to 30 days (4/53 [8%] vs. 0/20 [0%]), 14 to 60 days (23/136 [17%] vs. 0/36 [0%]), and 14 to 90 days (50/230 [22%] vs. 2/56 [4%]). In multivariate analysis, azithromycin-treated men had a significantly higher risk of persistent/recurrent infection in the 14 to 90 days (adjusted relative risk, 5.2; 95% confidence interval, 1.3-21.0) and 14 to 180 days (adjusted relative risk, 2.4; 95% confidence interval, 1.2-4.8) after treatment. CONCLUSIONS These data suggest that doxycycline may be more effective than azithromycin in the treatment of rectal chlamydial infections.

Abstract
OBJECTIVES The aim of the present study was to determine the Chlamydia trachomatis prevalence and to identify the demographic, behavioural and clinical factors associated with C. trachomatis in human immunodeficiency virus infected men. STUDY This was a cross-sectional study of C. trachomatis prevalence among human immunodeficiency virus-infected men enrolled at the Outpatient clinic of acquired immunodeficiency syndrome of the Fundação de Medicina Tropical Dr. Heitor Vieira Dourado in Manaus, Amazonas, Brazil. C. trachomatis deoxyribonucleic acid from urethral samples was purified and submitted to real time polymerase chain reaction to identify the presence of C. trachomatis. RESULTS A total of 276 human immunodeficiency virus-infected men were included in the study. The prevalence of C. trachomatis infection was 12% (95% confidence interval 8.1%-15.7%). The mean age of the participants was 34.63 (standard deviation 10.80) years. Of the 276 human immunodeficiency virus-infected men, 93 (56.2%) had more than one sexual partner in the past year and 105 (38.0%) reported having their first sexual intercourse under the age of 15 years. Men having sex with men and bisexuals amounted to 61.2% of the studied population. A total of 71.7% had received human immunodeficiency virus diagnosis in the last three years and 55.1% were using antiretroviral therapy. Factors associated with C. trachomatis infection in the logistic model were being single (p<0.034), men having sex with men (p<0.021), and having previous sexually transmitted diseases (p<0.001). CONCLUSION The high prevalence of C. trachomatis infection among human immunodeficiency virus-infected men highlights that screening human immunodeficiency virus-infected men for C. trachomatis, especially among men having sex with men, is paramount to control the spread of C. trachomatis infection.

Abstract
BACKGROUND The prevalence and correlates of rectal sexually transmitted infections are well described among men who report receptive anal intercourse (AI); however, little is known about the epidemiology of rectal sexually transmitted infections among women. METHODS We conducted a cross-sectional study of women attending public sexually transmitted disease clinics in Los Angeles County, California. Women were eligible for inclusion in this study if they reported AI in the previous 90 days, were tested for rectal chlamydia and gonorrhea, and were seen between January 2008 and December 2010. RESULTS Among the 2084 clinic visits by women in this analysis, chlamydia and gonorrhea percent positivity by anatomic site was 12% (n = 144) for urogenital chlamydia, 14.6% (n = 171) for rectal chlamydia, 3.3% (n = 66) for urogenital gonorrhea, and 3.0% (n = 60) for rectal gonorrhea, with 25% of chlamydia cases and 19% of gonorrhea cases having rectal-only infections. Among women 25 years or younger, rectal infections were higher in visits in which women reported sex with an injection drug user (46.5% vs. 15.5%; P < 0.01) or sex with a HIV-positive partner (66.7% vs. 15.8%; P = 0.02). Among women older than 25 years, rectal infections were higher in visits where women reported substance use (10.6% vs. 5.8%; P ≤ 0.01). In multivariable models controlling for age and the presence of a urogenital infection, these associations remained. CONCLUSIONS Chlamydia and gonorrhea positivity was high among women reporting AI, and a large proportion of these cases would be missed in the absence of rectal testing. The high-risk behaviors of women with rectal infections highlight the need for rectal screening recommendations.

Background. Community sampling of men having sex with men (MSM) for human immunodeficiency virus (HIV) and sexually transmitted infections prevalence studies poses challenges in view of problems in logistics and the hidden nature of MSM population. Methods. MSM in Hong Kong were recruited through social venues and the Internet. All participants were invited to complete a behavioural questionnaire and submit a urine specimen for HIV, Chlamydia, and gonorrhoea testing. Results. Totally, 994 MSM were recruited. No differences between venue and online-recruited respondents were identified regarding their demographics and infection status. The prevalence of HIV, Chlamydia, and gonorrhoea was 3.6% (95% CI: 2.6–5.0%), 4.7% (95% CI: 3.6–6.2%), and 0.2% (95% CI: 0.1–0.7%), respectively. Of all HIV cases, only 8.3% were aware of the infection; reflecting newly infected MSM were probably overrepresented. Some 58.3% had had HIV test within the past year, and 11.1% had CT/NG coinfection. HIV infection was associated with group sex [aOR: 2.67 (1.03–6.92)], receiving money for anal sex [aOR: 4.63 (1.12–19.18)], and unprotected anal sex with nonregular partners [aOR: 3.047 (1.16–8.01)]. Conclusion. Difference between venue- and online-recruited MSM was observed. A combination of sampling methods is complementary for epidemiology purpose. Overall, risk behaviours practised by undiagnosed HIV-positive MSM remains a cause for concern.

Vodstrcil LA, Fairley CK, Fehler G, Leslie D, Walker J, Bradshaw CS, Hocking JS. Trends in chlamydia and gonorrhea positivity among heterosexual men and men who have sex with men attending a large urban sexual health service in Australia, 2002-2009. BMC Infect Dis 2011; 11:158. [PMID: 21639943 PMCID: PMC3138447 DOI: 10.1186/1471-2334-11-158] [Citation(s) in RCA: 36] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2010] [Accepted: 06/05/2011] [Indexed: 11/11/2022] Open
Abstract
Background To determine whether chlamydia positivity among heterosexual men (MSW) and chlamydia and gonorrhea positivity among men who have sex with men (MSM), are changing. Methods Computerized records for men attending a large sexual health clinic between 2002 and 2009 were analyzed. Chlamydia and gonorrhea positivity were calculated and logistic regression used to assess changes over time. Results 17769 MSW and 8328 MSM tested for chlamydia and 7133 MSM tested for gonorrhea. In MSW, 7.37% (95% CI: 6.99-7.77) were chlamydia positive; the odds of chlamydia positivity increased by 4% per year (OR = 1.04; 95% CI: 1.01-1.07; p = 0.02) after main risk factors were adjusted for. In MSM, 3.70% (95% CI: 3.30-4.14) were urethral chlamydia positive and 5.36% (95% CI: 4.82-5.96) were anal chlamydia positive; positivity could not be shown to have changed over time. In MSM, 3.05% (95% CI: 2.63-3.53) tested anal gonorrhea positive and 1.83% (95% CI: 1.53-2.18) tested pharyngeal gonorrhea positive. Univariate analysis found the odds of anal gonorrhea positivity had decreased (OR = 0.93; 95% CI: 0.87-1.00; p = 0.05), but adjusting for main risk factors resulted in no change. Urethral gonorrhea cases in MSM as a percentage of all MSM tested for gonorrhea also fell (p < 0.001). Conclusions These data suggest that chlamydia prevalence in MSW is rising and chlamydia and gonorrhea prevalence among MSM is stable or declining. High STI testing rates among MSM in Australia may explain differences in STI trends between MSM and MSW.

Reactions to self-sampling for ano-rectal sexually transmitted infections among men who have sex with men: a qualitative study. ARCHIVES OF SEXUAL BEHAVIOR 2011; 40:281-288.

Abstract
Little is known about men's potential motivations and barriers associated with specific sexually transmitted infections (STI) testing methods. In this study, we examined experiences of self-sampling for ano-rectal STI among men who have sex with men (MSM) in a midwestern community in the U.S. A total of 75 MSM were recruited from community venues throughout Indianapolis, Indiana. Participants completed semi-structured interviews, were asked to obtain ano-rectal self-sample in a private restroom, and were asked open-ended questions about their experiences with ano-rectal self-sampling for STI. Participants included 35 White, 27 Black, and 13 Latino MSM who ranged in age from 18 to 57 years. Regardless of sexual practices, most participants who obtained an ano-rectal self-sample (68/75) reported that the sampling procedure was relatively painless and physically easy. However, regardless of previous receptive anal sex, participants also expressed concerns about the nature of the test (i.e., inserting something into their rectum), which required increased levels of privacy and cleanliness compared to collection of urine samples. Self-sampling proved to be a feasible and acceptable method of collecting ano-rectal STI specimens among MSM. Increased testing for ano-rectal STI among MSM may require addressing the location of sampling and testing sites, existing negative perceptions of ano-rectal self-sampling, and the measures in place to promote privacy and cleanliness.

Abstract
Background Racial/ethnic minorities and men who have sex with men (MSM) represent populations with disparate sexually transmitted infection (STI) rates. While race-specific STI rates have been widely reported, STI rates among MSM is often challenging given the absence of MSM population estimates. We evaluated the race-specific rates of chlamydia and gonorrhea among MSM and non-MSM in San Francisco between 1999-2008. Methods 2000 US Census data for San Francisco was used to estimate the number of African-American, Asian/Pacific Islander, Hispanic, and white males. Data from National HIV Behavioral Surveillance (NHBS) MSM 1, conducted in 2004, was used to estimate the total number of MSM in San Francisco and the size of race/ethnic sub-populations of MSM. Non-MSM estimates were calculated by subtracting the number of estimated MSM from the total number of males residing in San Francisco. Rates of MSM and non-MSM gonorrhea and chlamydia reported between 1999 and 2008 were stratified by race/ethnicity. Ratios of MSM and non-MSM rates of morbidity were calculated by race/ethnicity. Results Between 1999-2008, MSM accounted for 72% of gonorrhea cases and 51% of chlamydia cases. Throughout the study period, African-American MSM had the highest chlamydia rate with 606 cases per 100,000 in 1999 increasing to 2067 cases per 100,000 in 2008. Asian/Pacific Islander MSM consistently had the lowest rate among MSM with1003 cases per 100,000 in 2008. The ratio of MSM/non-MSM for chlamydia was highest among whites 11.6 (95% CI: 8.8-14.4) and Asian/Pacific Islanders 8.6 (95% CI: 6.2-11), and lowest among African-Americans 1.53 (95% CI: 1.2-1.9) and Hispanics 4.43 (95% CI: 2.8-6.0). Gonorrhea rates were similar for African-American, white, and Hispanic MSM between 2137-2441 cases per 100,000 in 2008. Asian/Pacific Islander MSM had the lowest gonorrhea rate with 865 cases per 100,000 in 2008. The ratio of MSM/non-MSM for gonorrhea was highest among whites 11.6 (95% CI: 8.8-14.4) and Asian/Pacific Islanders 8.6 (95% CI: 6.2-11), and lowest among African-Americans 1.53 (95% CI: 1.2-1.9) and Hispanics 4.43 (95% CI: 2.8-6.0). Conclusions For all racial/ethnic groups in San Francisco, MSM carried a substantially higher burden of STIs compared to non-MSM except among African-American men. These racial and sexual behavior disparities warrant further public health attention and resources.

Abstract
INTRODUCTION HIV infection continues to disproportionately affect men who have sex with men (MSM). Identification of modifiable risk factors for HIV infection among MSM is critical for effective prevention. METHODS We examined the relationship between number of prior rectal Neisseria gonorrhoeae (GC) or Chlamydia trachomatis (CT) infections and HIV seroconversion in a retrospective cohort of HIV-uninfected MSM diagnosed with a rectal infection. Number of rectal CT or GC infections in the prior 2 years was the primary exposure. Univariate and multivariate Cox proportional hazards models were used to estimate the association between prior rectal infections and HIV seroconversion. RESULTS A total of 541 MSM were observed for a total of 1197.96 person-years. Overall, 27 (4.99%) of the MSM became infected with HIV, for an estimated annual incidence of 2.25% [95% confidence interval (CI): 1.49 to 3.26]. In multivariate analysis, an early syphilis diagnosis in the past 2 years (hazard ratio = 4.04, 95% CI: 1.19 to 13.79) and 2 prior CT or GC rectal infections in the past 2 years (hazard ratio = 8.85, 95% CI: 2.57 to 30.40) were associated with incident HIV. CONCLUSIONS Among MSM infected with rectal GC or CT, a history of 2 additional prior rectal infections was associated with an 8-fold increased risk of HIV infection. HIV-uninfected MSM with multiple rectal infections represent a population in need of innovative HIV-prevention interventions.

Abstract
BACKGROUND The Centers for Disease Control recommend screening for asymptomatic sexually transmitted infection (STI) among HIV-infected men when there is self-report of unprotected anal-receptive exposure. The study goals were: (1) to estimate the validity and usefulness for screening policies of self-reported unprotected anal-receptive exposure as a risk indicator for asymptomatic anorectal infection with Neisseria gonorrhoeae (GC) and/or Chlamydia trachomatis (CT). (2) to estimate the number of infections that would be missed if anal diagnostic assays were not performed among patients who denied unprotected anorectal exposure in the preceding month. METHODS AND FINDINGS Retrospective analysis in HIV primary care and high resolution anoscopy (HRA) clinics. HIV-infected adult men were screened for self-reported exposure during the previous month at all primary care and HRA appointments. Four sub-cohorts were defined based on microbiology methodology (GC culture and CT direct fluorescent antibody vs. GC/CT nucleic acid amplification test) and clinical setting (primary care vs. HRA). Screening question operating characteristics were estimated using contingency table methods and then pooled across subcohorts. Among 803 patients, the prevalence of anorectal GC/CT varied from 3.5-20.1% in the 4 sub-cohorts. The sensitivity of the screening question for self-reported exposure to predict anorectal STI was higher in the primary care than in the HRA clinic, 86-100% vs. 12-35%, respectively. The negative predictive value of the screening question to predict asymptomatic anorectal STI was > or = 90% in all sub-cohorts. In sensitivity analyses, the probability of being an unidentified case among those denying exposure increased from 0.4-8.1% in the primary care setting, and from 0.9-18.8% in the HRA setting as the prevalence varied from 1-20%. CONCLUSION As STI prevalence increases, denial of unprotected anal-receptive exposure leads to an increasingly unacceptable proportion of unidentified asymptomatic anorectal STI if used as a criterion not to obtain microbiologic assays.

Abstract
The cost-effectiveness of screening men for Chlamydia trachomatis depends in part on the prevalence of chlamydia in the screened population and the ease with which screening programs can be implemented. Screening in venues with high rates of chlamydia positivity among men may therefore be an important adjunct to chlamydia control. To evaluate the recent US literature on chlamydia positivity in chlamydia screening programs among asymptomatic men in nonsexually transmitted disease clinic settings, we reviewed published articles between 1995 and June 2007, using PubMed as the primary search tool. Articles were abstracted and positivity rates summarized by type of venue, race/ethnicity, age group, and US region. The overall median positivity rate was 5.1%. The highest rates were observed among men tested in juvenile (7.9%) and adult (6.8%) detention facilities, among blacks (6.7%), the 15 to 19 years old (6.1%) and 20 to 24 years old (6.5%) age groups, and among men screened in the southern United States (6.4%). Chlamydia rates among men are high in certain venues, particularly correctional settings, but also depend on the demographic composition of the target population and location. Programs considering male chlamydia screening programs should conduct pilot programs to assess chlamydia positivity as well as feasibility and cost in target venues.

Abstract
To assess the prevalence of asymptomatic urethral gonorrhea and chlamydia men who have sex with men (MSM) living in greater Boston, 206 men attending routine medical appointments consented to urine-based chlamydia and gonorrhea screening using urine LCR amplification. Of those screened, 201 patients also completed a seven-question survey to assess sexual risk behaviors associated with urethral sexually transmitted infections. Less than 1% of the asymptomatic patients screened tested positive for urethral chlamydia; none tested positive for urethral gonorrhea. Forty-eight percent reported multiple sexual partners in the 30 days prior to screening, with HIV-infected patients reporting fewer partners and less unprotected insertive anal sex than HIV-uninfected patients. Almost 25% of patients screened used the Internet in the 30 days prior to screening to find a sexual partner. Internet use was associated with increased numbers of sexual partners in the 30 days prior to screening. Findings suggest that asymptomatic urethral chlamydia and gonorrhea may be uncommon in MSM living in the greater Boston area and that the recent rise in the prevalence of sexually transmitted infections may not be due to untreated asymptomatic infections. Increased awareness of STD symptoms among patients and medical providers is critical to timely diagnosis and treatment of STDs in MSM.

Abstract
OBJECTIVES This study aimed to investigate the prevalence of human immunodeficiency virus (HIV) and sexually transmitted infections (STIs) and predictors of risky sexual behaviors among men visiting gay bathhouses. STUDY DESIGN A cross-sectional study was conducted at 8 gay bathhouses in Taiwan. Bathhouse attendees were invited to complete a questionnaire and to be screened for HIV/STIs. RESULTS Of 451 men recruited for the study, 339 (75%) completed the questionnaire and were screened for HIV/STIs. The study indicated that seroprevalence rates of anti-HIV-1 antibody, specific Treponema pallidum antibodies detected by hemagglutination assay, surface antigen of hepatitis B virus, IgG antibodies for hepatitis A virus, antibody for hepatitis C virus, and indirect hemagglutination antibody for Entamoeba histolytica (serum titer > or =1:128) were 8%, 18%, 16%, 38%, 3%, and 6%, respectively. Prevalence rates for chlamydial and gonococcal infections reflected by nucleic acid amplification tests in urine samples were 7% and 4%, respectively. Irregular use of condoms during oral sex, condom inaccessibility at bathhouses, unprotected sex at public venues, no prior HIV test, and 5 or more visits to bathhouses every month were independently associated with unprotected anal intercourse. CONCLUSION Men attending gay bathhouses report engaging in unsafe sex practices and are at substantial risk of acquisition of HIV/STIs. These findings highlight the need for more comprehensive prevention efforts at gay bathhouses.

Abstract
The Centers for Disease Control (CDC) recommends sexually transmitted disease (STD) screening among HIV-infected persons in order to reduce HIV transmission. We evaluated the results of routine screening for syphilis and for urogenital, pharyngeal, and rectal gonorrhea (GC) and chlamydia (CT) among asymptomatic HIV-infected patients at an HIV primary care clinic in San Francisco, California. We found 15 new syphilis infections of 814 tested (1.8%) and 60 new cases of CT or GC infection of 586 tested (10.2%), with 88% of GC and CT infections occurring at nonurethral sites. Our study reveals a high rate of asymptomatic STDs among HIV-infected patients in primary care and supports the CDC recommendations to screen HIV-infected patients for STDs at all relevant anatomic sites.

Abstract
BACKGROUND The Centers for Disease Control and Prevention developed screening and diagnostic testing guidelines for chlamydia and gonorrhea at urethral, rectal, and pharyngeal sites for men who have sex with men (MSM). However, in most clinical settings, rectal chlamydial testing is not performed for MSM, and primarily sexually transmitted disease (STD) clinics alone perform routine rectal and pharyngeal gonorrhea screening for asymptomatic men. METHODS We evaluated the prevalence of rectal, urethral, and pharyngeal chlamydial and gonococcal infections among MSM seen at the municipal STD clinic and the gay men's community health center. We also determined the proportion of asymptomatic rectal infections, described the patterns of single and multiple anatomic sites of infection, and evaluated the proportion of chlamydial infections that would be missed and not treated if MSM were not routinely tested for chlamydia. We tested specimens using previously validated nucleic acid amplification tests (NAATs). RESULTS The prevalence of infection varied by anatomic site (chlamydia: rectal, 7.9%; urethral, 5.2%; and pharyngeal, 1.4%; for gonorrhea, rectal, 6.9%; urethral, 6.0%; and pharyngeal, 9.2%). Approximately 85% of rectal infections were asymptomatic supporting the need for routine screening. Because 53% of chlamydial infections and 64% of gonococcal infections were at nonurethral sites, these infections would be missed and not treated if only urethral screening was performed. In addition, >70% of chlamydial infections would be missed and not treated if MSM were tested only for gonorrhea. CONCLUSIONS Because these infections enhance both HIV transmission and susceptibility, clinical settings serving MSM should evaluate the prevalence of chlamydial and gonococcal infections by anatomic site using validated NAATs.

Abstract
Objectives: To determine by systematic review the prevalence of genital chlamydial infection in Australia between 1997 and 2004. Methods: Electronic literature databases, reference lists, and conference proceedings were searched and health agencies and jurisdictions were contacted for published and unpublished reports. Studies were eligible if they offered a diagnostic nucleic acid amplification test to consecutive individuals presenting during the study period. As a summary measure of the available data, mean prevalence rates, weighted by sample size and irrespective of participant age, were calculated for the population sub-groups. Results: 40 studies of 50 populations and 40587 individuals met the inclusion criteria, but only one of these was population-based. The use of non-systematic methodologies prevented an assessment of time trends and a statistical comparison of population sub-groups. The mean overall prevalence of genital chlamydial infection was 4.6% (95% CI 4.4–4.8%), reflecting over-sampling of high-risk groups. The mean community-based rates were 7.5% (95% CI 6.4–8.6%) and 8.7% (95% CI 7.9–9.7%) for Indigenous men and women, and 1.5% (95% CI 1.1–1.9%) and 1.4% (95% CI 0.9–2.0%) for non-Indigenous men and women. The overall mean estimates for other groups were 3.3% (95% CI 3.0–3.7%) for female attendees of sexual health and related clinics, 5.6% (95% CI 4.9–6.4%) for adolescents and young adults, 3.3% (95% CI 2.8–3.9%) for sex workers, and 1.6% (95% CI 1.2–2.0%) for urethral infection in men who have sex with men. Clinic-based estimates were generally, although not consistently, higher than community-based estimates. There is no serial population-based data for sexually active young men and women, but the available age-specific rates suggest under-ascertainment by the routine surveillance systems. Conclusions: The prevalence of genital chlamydial infection in Indigenous Australians and young adults is unacceptably high and quality epidemiological studies are urgently required to supplement the routinely collected national notification data.

Abstract
The study aims were to evaluate the prevalence and predictors of sexual risk behaviors and urethral sexually transmitted disease (STD) among males entering care for HIV infection and to examine if sildenafil prescriptions are associated with potentially transmitting sexual risk behavior (PTSRB). The research design included (1) self-administered questionnaire of symptoms of sexually transmitted infection (STI), number of recent sex partners, unprotected sexual risk behaviors, use of drugs/alcohol during sex, and HIV disclosure; (2) urine gonorrhea/chlamydia polymerase chain reaction (PCR); and (3) record review for sildenafil prescriptions. A PTSRB was defined as insertive anal, vaginal, or oral sex without a condom. Between March 2001 and March 2002, 413 entrants were surveyed. The prevalence of positive urine PCR among those with and without urethral symptoms was 16.7% and 2.4%, respectively. Fifty-one percent met criteria for PTSRB during the preceding month. Those reporting PTSRB were more likely to report multiple partners. In a multiple logistic regression model, the following were significant (p < 0.05) predictors of PTSRB: drug or alcohol use during sex; white race; only male partners, and sildenafil use. Drug use during sex was associated both with more sex partners and more sexual risk behaviors. Always disclosing HIV status was associated with fewer partners. There was a high prevalence of PTSRB among HIV-infected males entering care. Men who have sex with men (MSM), white race, drug/alcohol use during sex, and sildenafil use were independent risk factors. PTSRB was associated with having multiple partners. Physicians should discuss risk behaviors before prescribing sildenafil.

Abstract
During the past several years, research related to screening for Chlamydia trachomatis has flourished, with new diagnostic tests, new methods for specimen collection, and new prevalence data in different populations. Public health endorsements for screening are now more specific than ever, yet several important clinical and laboratory questions remain, including questions concerning who to screen and how often to screen. Additional important research is addressing issues related to assay validity, efficacy of screening in different populations, and feasibility of screening on the level of the individual patient and the level of the community and health care system. This article discusses major research findings related to chlamydial screening from the past several years and suggests areas in which additional research is needed.

Abstract
Increases in sexually transmitted diseases (STDs) among men who have sex with men (MSM) have coincided with recent increases in sexual risk behaviors across the United States and Europe. The identification of same-sex sexual risk behavior in men and the subsequent risk for certain bacterial and viral infections requires competency in taking a sexual history. Recent advances in the diagnosis and treatment of STDs have made STD management easier for physicians and patients and expanded the ability of a variety of health care professionals to participate in the management of STDs. This review focuses on recent developments in the epidemiology, pathogenesis, diagnosis, and management of common STDs in MSM.
