Objectives: In the industrialized world, lymphogranuloma venereum proctitis (LGVP) has been reported only in men who have sex with men. Factors responsible for the outbreak remain to be elucidated. GOAL: The goal of the present work was to elucidate risk factors associated with LGVP. Study Design: The study design comprised a cross-sectional study including 32 men with LGVP and 93 men without LGVP (22 with gonorrheal proctitis, 30 with a non-LGV chlamydial proctitis, and 41 with proctitis of unknown etiology). Factors associated with LGVP were analyzed by (multinomial) logistic regression. Results: Comparing men with LGVP with men without LGVP, factors significantly associated with higher risk of LGVP in multivariate analyses were as follows: anal enema use [odds ratio (OR): 7.8, 95% confidence interval (CI): 2.6-23.2], having sex on sex parties (OR: 5.7, 95% CI: 1.5-21.8), and having sex with human immunodeficiency virus-positive partners (OR: 3.2, 95% CI: 1.1-9.3). Evaluating the 4 proctitis groups separately in a multinomial logistic regression model, similar associations between anal enema use and LGVP were found. Men with non-LGV chlamydial proctitis showed less risk behavior than men with LGVP. No substantial difference in risk behavior was found, except for attending sex parties, between men with LGVP, and gonorrheal proctitis or proctitis of unknown etiology. Conclusions: Apart from men with LGVP, men with gonorrheal proctitis or proctitis of unknown etiology exhibit high risk behavior. Enema use seems to play a key role in transmission of LGVP, and needs further investigation.

Background and Objectives: In response to increases in sexually transmissible infections (STI) and HIV infection rates among men who have sex with men (MSM), the current study aimed to investigate the feasibility of a screening program at male-only saunas in Melbourne, Australia. Goal: The goal was to determine (1) the participation rate, and the proportion whom obtain test results; (2) the prevalence of gonorrhea and chlamydia; and (3) to evaluate risk factors for STI acquisition. Study Design: We used a cross-sectional design. Pharyngeal, rectal, and urethral specimens were collected from participants, and tested for Chlamydia trachomatis and Neisseria gonorrhoeae by polymerase chain reaction (PCR). Results: There was a participation rate of 24% (n = 521), and 70% obtained their test results. The infection rate in those who failed to collect their results was no different than those seeking theirs. The proportion of participants with PCR-detected gonorrhea and/or chlamydia infection was high, 10.7%. The presence of infection was associated with seeking sexual health care in the last year. Conclusion: The high prevalence rate of gonorrhea and chlamydia supports the concept of a screening program in Melbourne male-only saunas. The low participation rate has highlighted the need to consider alternative methods for making contact with men in the saunas or offering incentives to participate in future screening programs. Although anonymous participation encouraged participation for some men, future programs should attempt to obtain contact details for follow up of positive test results.

Background: Spain has been the European country most affected by the AIDS epidemic, and sexual transmission now accounts for the majority of cases of HIV. Goal: The goal was to describe HIV prevalence and risk profiles among people tested for HIV in Barcelona in 1998 to 2001. Study Design: We studied cross-sectional HIV surveys among sexually transmitted infection clinic attenders. We performed quantification of risk factors for HIV infection through odds ratios (ORs) and logistic regression. Results: The prevalence of HIV among the 4993 persons tested was 1.8% (95% confidence interval, 1.5-2.2) without significant changes across the years. HIV prevalence in homo-/bisexual men was higher (P Conclusion: HIV prevalences were relatively low among all heterosexuals, but much higher among homosexual and bisexual men. The potential exists for ongoing sexual HIV transmission among homo-/ bisexual men in Barcelona.

Background: Recent increases in rates of sexually transmitted diseases (STDs) and decreases in safe sex behaviors among men who have sex with men (MSM) in several American and European cities have been noted by researchers. It has been suggested that these trends are the result of perceptions that HIV/AIDS is less serious because of the availability of highly active antiretroviral therapy (HAART). Goal: The goal of the study was to examine trends in STD rates and risk behaviors among MSM and men who have sex with women (MSW) visiting a public STD clinic in Denver and to determine whether there is an ecological association with the availability of HAART. Study Design: This is a two-part retrospective analysis of male visits to the Denver Metro Health Clinic (DMHC). The first part describes gonorrhea and early (primary and secondary) syphilis trends among MSM between 1982 and 2001. For the second part, data were grouped into two 6-year time periods to represent pre-HAART and post-HAART time frames, 1990 to 1995 and 1996 to 2001. Results: Gonorrhea and early syphilis cases among MSM declined precipitously between 1982 and 1988 and then stabilized at low rates. The proportion of male visits to the clinic made by MSM decreased from 14.1% in 1990 to 7.2% in 1995 and then increased to 13.0% in 2001. Gonorrhea positivity rates among MSM increased after 1995 and were significantly higher in the period 1996 to 2001 (12.9%) than in the period 1990 to 1995 (8.1%; P < 0.0001). Conversely, gonorrhea rates among MSW dropped from 11.2% in the first period to 6.9% in the second (P < 0.0001). Among MSM known to be HIV-infected, gonorrhea rates increased from 11.6% in the first time period to 24.0% in the second period (P < 0.0001). Reports of anal sex among MSM increased from 64.4% to 70.9% (P < 0.0001). Reporting more than one sex partner increased for MSM from 65.2% to 70.3% (P < 0.0001), but it significantly decreased from 52.6% to 46.2% for MSW (P < 0.0001). No or inconsistent condom use increased from 60.9% to 63.0% for MSM (P = NS) and decreased from 85.1% to 82.4% among MSW (P < 0.0001). Conclusions: These trends appear to reflect a change toward higher risk-taking behaviors among MSM but not MSW since the time HAART became available and raise concerns about the potential for increased HIV transmission in this group.

Background: Despite national ambitions to eliminate syphilis, occasional outbreaks continue to occur in many areas of the United States. Goal: The goal of the study was to describe and evaluate the public health interventions in response to an outbreak of syphilis in Los Angeles County among men who have sex with men. Study Design: Reported cases of primary, secondary, and early latent syphilis that occurred during an outbreak period from December 1999 to September 2000 were included in the study. The outbreak components of provider awareness, active surveillance, community-based organization recruitment, media campaign, community-outreach education and screening, and a correctional facility intervention were described. Screening results were reviewed, sexually transmitted disease (STD) hotline calls were counted, and a street-intercept survey was conducted. Results: A multifaceted outbreak response was initiated in March 2000. Of the 89 outbreak cases identified, 40% were detected by HIV/AIDS early intervention providers and 26% by private clinicians or health maintenance organizations. Other case identification sources included public STD clinics (10%), STD program case-management contacts (7%), mobile van screening (7%), and correctional facility screening (10%). Screening at high-risk venues detected a syphilis prevalence of Conclusions: A multifaceted outbreak response was launched to react to an outbreak of syphilis among men who have sex with men. Prompt provider awareness and a preexisting network of HIV/AIDS providers aided ease detection. Although the effectiveness of the response could not be scientifically determined, the diverse components of the response were associated with a faster decline in the outbreak than would have been expected. After 3 months, 89 cases had been identified. Outbreak preparedness should include a focus on communities of men who have sex with men, because the reintroduction of syphilis in this population may threaten national efforts toward syphilis elimination.

Background: Bacterial sexually transmitted diseases (STDs) among men who have sex with men (MSM) have recently increased in Seattle. Goals: Serovar and auxotype typing of strains was used to assess the epidemiology of anorectal chlamydial and gonococcal infections among MSM attending an STD clinic. Study Design: The prevalences of anorectal chlamydial infection and gonorrhea among MSM attending an STD clinic during the period of 1994 to 1996 were compared with prevalences during 1997 to 1999. A retrospective case-control study of MSM attending an STD clinic between 1997 and 1999 was performed. Anorectal chlamydial isolates were characterized by serovar and gonococcal isolates were characterized by serovar and auxotype. Infected MSM were mapped by residence and strain type. Results: Prevalences of anorectal chlamydial and gonococcal infections increased from 4.0% and 6.3%, respectively, during 1994-1996 to 7.6% and 8.7%, respectively, during 1997-1999 (P = 0.004 and P = 0.013 for chlamydial infection and gonorrhea, respectively). Most chlamydial infections were caused by serovars G (47.9%) and D (29.6%), and most gonococcal infections were caused by auxotype/serovar classes Proto/IB-1 (43.3%), Proto/IB-3 (16.5%), and Proto/IB-2 (10.3%). MSM with anorectal chlamydial infection more often had chlamydial urethritis (P = 0.005) and were not white (P = 0.046), in comparison with controls. MSM with anorectal gonorrhea more often had pharyngeal gonorrhea (P < 0.001), had a history of gonorrhea (P = 0.003), and were younger than age 30 years (P = 0.039), in comparison with controls. Residences of MSM with anorectal gonorrhea were clustered in urban areas, whereas those of MSM with anorectal chlamydial infection were more dispersed. Conclusion: Prevalences of anorectal chlamydial infection and gonorrhea among MSM in Seattle have increased dramatically over the past 3 years. Serovar and auxotype analyses indicate these increases are not clonal but are due to the spread of unique distributions of strains that differ from those causing urogenital infections in the same community.

Background: To assess the prevalence and increase awareness of Neisseria gonorrhoeae and Chlamydia trachomatis infections among men who have sex with men, a screening program was conducted at three inner-city homosexual entertainment venues and one community function. Study Design: Each venue was accessed twice over a 3-month period between March and June 2000. First-catch urine specimens were collected for analysis by polymerase chain reaction (PCR), and throat swabs were collected for culture and PCR. Results: A total of 202 men were tested during the 7 screening nights, including 16 who were tested more than once. From the 186 men tested for the first time, 184 urine specimens were collected, of which 8 (4.3%; 95% CI, 1.9-7.8%) were PCR-positive for C trachomatis and 1 (0.5%; 95% CI, 0-2.1%) was PCR-positive for N gonorrhoeae. Of the 161 throat swabs collected, none were positive for C trachomatis or N gonorrhoeae. Conclusions: C trachomatis is a potentially significant pathogen in this population of urban homosexual men. Screening programs such as these are valuable as health-promotion exercises.

Background: Previous data indicating wide racial disparities in HIV seroprevalence, associations between sentinel sexually transmitted diseases (STDs) and HIV infection, and recent reports of STD outbreaks among men who have sex with men (MSM) have raised concerns that HIV may be resurgent among MSM. Goal: To measure trends in HIV seroprevalence and describe racial disparities among MSM presenting to New York City Department of Health STD clinics, 1990-1999 (n = 4076). Study Design: This blinded HIV-1 serosurvey used remnant serum originally drawn for routine serologic tests for syphilis. Demographic, risk factor, clinical and laboratory data were abstracted from clinic charts of patients whose medical records documented sexual contact with men or with both men and women ('bisexual' men). Data were matched to the specimens, and all personal identifiers were removed before testing. Patients were not interviewed. Results: The sample was 41% black, 20% Hispanic, 31% white, and 9% of other or mixed race/ethnicity. Sixty-one percent of the patients were >30 years of age; 21% were [greater than or equal to] 40 years of age. One-third had sex with women as well as men. For 60%, laboratory-confirmed STD diagnosis was made on the serosurvey visit. Overall, HIV seroprevalence declined from 47% in 1990 to 18% in 1999 (P < 0.01). Seroprevalence declined from 34% to 11% among white men (n = 1250), from 47% to 19% among Hispanic men (n = 795), from 56% to 28% among black men (n = 1656), and from 43% to 14% among men who had sex with both men and women (n = 1447). Seroprevalence among MSM with gonorrhea (n = 507) declined but remained high (57-34%; P < 0.05). In contrast, seroprevalence among MSM with non-gonococcal urethritis (n = 953) declined from 36% to 16% (P < 0.01), and seroprevalence among MSM who had no STD (n = 1650) dropped from 48% to 12% (P < 0.01). Gonorrhea was diagnosed almost twice as frequently among seropositive versus seronegative MSM (19% versus 10%; P < 0.05). Black MSM were not more or less likely to have been tested for HIV or to be diagnosed with acute STD than were MSM in the other-race/ethnicity group. Positive serostatus was associated with black race/ethnicity (odds ratio [OR], 2.5; 95% CI, 2.1-2.9), age >25 years (OR, 2.5; 95% CI, 1.9-3.1), and a diagnosis of gonorrhea (OR, 2.4; 95% CI, 2.0-2.8). Sixty percent of seropositive MSM knew their serostatus from confidential or anonymous HIV testing at this or a previous visit. Two thirds of the known seropositive men had a new STD diagnosed at the serosurvey visit. Conclusion: Seroprevalence in this racially diverse sample of MSM declined significantly during the study period. However, wide racial disparities in seroprevalence were observed that were not attributable to disparities in risk factors such as STD, bisexuality, or acceptance of HIV testing. This finding suggests that the observed differences may reflect racial differences in the background seroprevalences, such as those seen in all New York City serosurvey samples and the population-based AIDS case rates. High prevalence associated with gonorrhea and new STD in known seropositive men of any race suggests that continued efforts to control the incidence of STD, increased encouragement of MSM to accept HIV counseling and testing, and prevention-focused counseling of seropositive men are needed.

Objectives: We hypothesized that men in a relationship would engage in less risky sexual activity with their casual partners compared to men with only casual partners. Study: Cross-sectional data were collected between 1999 and 2003 in a study of young human immunodeficiency virus-seronegative gay men in Vancouver, British Columbia. We assessed the substance use and sexual behaviors of 156 men and compared those having casual partners in addition to 1 regular partner for the duration of the previous year (n = 43) to those reporting only casual partners during the previous year (n = 113). Results: Men with just 1 regular partner were not significantly different from men without a regular partner with regard to sexual behaviors reportedly engaged in with casual partners, self-reported sexually transmitted infections diagnosed within the previous year, or demographic characteristics. Only previous use of poppers and higher frequencies of marijuana use were found among men without a regular partner. Conclusions: In our cohort, young gay men in a relationship do not appear less likely to engage in risky sex with casual partners than men with casual partners only.

Background: The modes of transmission of human herpesvirus 8 (HHV-8) remain unclear. Goal: To study HHV-8 seroprevalence and risk factors among young men. Study Design: The Young Men's Survey was a multisite cross-sectional HIV seroprevalence and behavioral risk survey of men aged 15 to 22 years who attended public venues frequented by young men who have sex with men (MSM). Blood specimens were tested for HHV-8 by using an immunofluorescence assay at a 1:40 dilution among 488 participants in Seattle-King County, WA. Results: Total HHV-8 seroprevalence was 6% among MSM and 5% among men who have sex only with women (MSW). In multivariate analysis, unprotected receptive anal sex during the past 6 months, injection drug use, and cytomegalovirus infection were associated with HHV-8 seropositivity in MSM. Conclusion: The HHV-8 seroprevalence among these young MSM was similar to the HHV-8 seroprevalence among young MSW, but lower than seroprevalence estimates in earlier studies of older MSM. The association of MSM between HHV-8 infection and unprotected receptive anal sex supports previous findings that HHV-8 is sexually transmitted. Although CMV infection and injection drug use may be markers for unsafe sexual practices, it is also possible that these are independent risk factors for acquiring HHV-8.

Background: Evidence of an STD-HIV interaction and the availability of noninvasive urine-based screening tests have resulted in an increased focus on chlamydial infections in men. Goal: To evaluate the prevalence of chlamydial infections among men with urethritis at the San Francisco City Clinic (SFCC). Study Design: In 1997, male SFCC patients diagnosed with urethritis were tested for chlamydia using urine-based ligase chain reaction and for gonorrhea using urethral culture. Results: Gonorrhea was identified in 45% of men who have sex with men (MSM) versus 26% of men who have sex with women (MSW). Among men with gonorrhea, chlamydia coinfection was found among 15.2% of MSM and 8.4% of MSW. Among men with nongonococcal urethritis, 18% and 20% of MSM and MSW had chlamydial infection, respectively. Young age was associated with chlamydial infection in MSM. Conclusion: After a period of low chlamydiai infection rates in MSM during the pre-AIDS era, infection rates are increasing among this population. SFCC's revised clinical practice guidelines include chlamydia testing of MSM with urethritis., More and more gay men are becoming infected with chlamydia, which is a sexually transmitted disease. It can occur in conjunction with other STDs, such as gonorrhea and non-gonococcal urethritis.

A recent article by Handsfield and Schwebke in the Oct-Dec 1990 issue of Sexually Transmitted Diseases reports that the rate of sexually transmitted diseases (STD) is again rising among homosexual men in Seattle. This is discouraging, as STD rates had declined in this group through the 1980s, following intensive education on behavioral risks for infection with HIV (human immunodeficiency virus, the cause of AIDS) and other STDs. Rates had declined in many groups, but the drop among homosexual men had been much greater. This had led to the hope that efforts to change behavior were a good way to achieve control of STD transmission. The Seattle report most likely indicates a failure to sustain altered behavior by homosexual men. Although one third of the group studied was under 24 years old and thus probably less aware and less concerned when AIDS began to affect the homosexual population, the remainder of the group was over 24, suggesting that a behavioral relapse was occurring. Whether this was due to perception of a decreased risk in themselves or their partners or whether other perceptions were involved is an essential topic for further research. The shift of public educational efforts from homosexual men to drug users and other high-risk groups may also have contributed to the increased rate, and it may become necessary to calculate the cost associated with maintenance of low-risk behaviors. The contribution of altering sexual behavior toward slowing STD transmission was not valued before the advent of AIDS. The trend reported in this article is an illustration of the significance of behavior not only among homosexual men but in other groups as well. More research on the effectiveness of decreasing risk by decreasing desirability of high-risk behaviors rather than relying upon the fear of AIDS as a deterrent, is greatly needed.
