We aimed to determine the frequency of T pallidum shedding from potentially asymptomatic sites and the stage of infection at which shedding is most frequent in men who have sex with men (MSM), who have been disproportionately affected by syphilis.
Methods: We did a prospective, cross-sectional study in MSM recruited from Melbourne Sexual Health Centre (Melbourne, VIC, Australia).
Background: Serology is negative in a proportion of primary syphilis cases where PCR testing is positive. We aimed to identify discordant, PCR-positive, serology-negative primary syphilis cases and any clinical or laboratory factors associated with failure to subsequently seroconvert.
Methods: Serodiscordant primary syphilis cases that were PCR-positive and serology-negative (including rapid plasma reagin, particle agglutination, enzyme immunoassay or chemiluminescence assay) were identified from the Melbourne Sexual Health Centre electronic records between April 2011 and December 2019.
Background: Current international guidelines on human immunodeficieny virus (HIV) Pre-Exposure Prophylaxis (PrEP) recommend serological screening for syphilis at routine 3-monthly PrEP appointments. The aim of our study was to describe the pattern of clinical presentation of syphilis among men who have sex with men (MSM) taking PrEP. We were interested in whether syphilis is detected through screening at scheduled3-monthly PrEP clinic appointments or whether primary or secondary syphilis presented at unscheduled interval visits.

Methods: Clinical, demographic, laboratory and behavioural data on MSM presenting for HIV testing at the Melbourne Sexual Health Centre from July 2013 to June 2017 were extracted. We compared the proportion of newly-arrived (four years or less in Australia), Asian-born and other MSM tested each year who were diagnosed with incident HIV infection (negative test within one year or diagnosis with indeterminate or negative Western Blot).
Background: Syphilis infections continue to increase among men who have sex with men (MSM) in many countries, with rates often higher among HIV-positive MSM. There is limited understanding of the risk and determinants of syphilis transmission between men. We aimed to examine the concordance of early syphilis infection between male sexual partners and clinical factors associated with transmission.

Objectives: We examined the time from HIV infection to virological suppression in MSM who were first diagnosed at Melbourne Sexual Health Centre between 2007 and 2016.
Design: Retrospective cohort.
Background: This before-and-after study measured the impact of a change in testing methods from culture to nucleic acid amplification testing (NAAT) on the detection of pharyngeal and rectal gonorrhea in men who have sex with men (MSM) on a sexual health service level, including the effect on subgroups anticipated to have higher rates of gonorrhea.
Methods: In March 2015, Melbourne Sexual Health Centre changed its laboratory method for gonococcal testing from culture to NAAT using the Aptima Combo 2 and Aptima GC tests. We compared the proportion of tests positive for rectal and pharyngeal gonorrhea in MSM using culture in 2014 with those using NAAT in 2015.
Introduction: The aim of this study was to determine the risk factors for HIV infection and the incidence in men who have sex with men (MSM). It is important to identify subgroups of MSM in which preventive interventions such as pre-exposure prophylaxis (PrEP) offered at the time of their last negative test would be considered cost-effective.
Methods: We conducted a retrospective cohort study of MSM attending Melbourne Sexual Health Centre (MSHC) during 2007-2013 with at least two HIV tests within 12 months of each other.
Background: The aim of this study was to characterise the clinical features of adenovirus urethritis in men and to compare the frequency of these between heterosexual men and men who have sex with men (MSM).
Methods: This was a review of the clinical and laboratory information from men diagnosed with PCR-confirmed adenovirus urethritis at the Melbourne Sexual Health Centre between January 2006 and April 2014.
Results: 102 adenovirus urethritis cases were reported, among which 61 were heterosexual men and 41 MSM.
Background: Chancres, the hallmark of primary syphilis, are classically described as single, painless ulcers at the site of Treponema pallidum inoculation. We aimed to determine the frequency of painful or multiple anogenital lesions of primary syphilis among men, whether there was concurrent herpes simplex virus (HSV) infection and whether HIV status altered clinical presentations.
Methods: This study was conducted among men with T.
Unlabelled: Background Increasing the frequency of HIV testing in men who have sex with men (MSM) will reduce the incidence of HIV. Trends in HIV testing among MSM in Melbourne, Australia over the last 11 years have been investigated.
Methods: A retrospective study was conducted using electronic medical records of the first presentation of MSM who attended the Melbourne Sexual Health Centre between 2003 and 2013.
Background: This study aimed to determine the prevalence of gonorrhoea and factors associated with rectal gonorrhoea among men reporting sexual contact with men with gonorrhoea.
Methods: Men who presented to Melbourne Sexual Health Centre reporting sexual contact with a male with gonorrhoea were prospectively identified between March 2011 and December 2013. These men were screened for pharyngeal and rectal gonorrhoea using culture.
The rapid rise in syphilis cases has prompted a number of public health campaigns to assist men who have sex with men (MSM) recognize and present early with symptoms. This study aimed to investigate the temporal trend of the duration of self-report symptoms and titre of rapid plasma reagin (RPR) in MSM with infectious syphilis. Seven hundred and sixty-one syphilis cases in MSM diagnosed at the Melbourne Sexual Health Centre (MSHC) from 2007-2013 were reviewed.
View Article and Find Full Text PDFObjectives: To examine whether the rapid increase of gonorrhoea notifications in Victoria, Australia, identified by nucleic acid amplification test (NAAT) is supported by similar changes in diagnoses by culture, which has higher specificity, and to determine the proportion of tests positive among women tested.
Design, Setting And Participants: Retrospective analysis of Medicare reporting of dual NAATs in Victoria, Victorian Department of Health gonorrhoea notifications, and gonorrhoea culture data at the Melbourne Sexual Health Centre (MSHC), among women, 2008 to 2013.
Main Outcome Measures: Gonorrhoea notifications and testing methods.
Background: Most syphilis point-of-care (POC) tests detect treponemal antibodies, which persist after successful treatment. Subsequent POC tests are positive, despite no active infection, and can lead to unnecessary treatment. We evaluated a new POC test, incorporating a nontreponemal component, to distinguish active from past infection.

Methods: Gonorrhea and chlamydia positivity by anatomical site adjusted for year of test, age, number of sexual partners, and condom use among MSM attending Melbourne Sexual Health Centre from 2007 to 2013 were calculated using generalized estimating equation regression models.
Results: A total of 12,873 MSM were included with a median age of 30.
Background: The frequency of testing sex workers for sexually transmitted infections (STIs) in Victoria, Australia, was changed from monthly to quarterly on 6 October 2012. Our aim was to determine the impact of this change to the clients seen at the Melbourne Sexual Health Centre (MHSC).
Methods: Computerised medical records of all clients attending at MHSC from 7 October 2011 to 7 October 2013 were analysed.
Background: Syphilis point-of-care tests may reduce morbidity and ongoing transmission by increasing the proportion of people rapidly treated. Syphilis stage and co-infection with HIV may influence test performance. We evaluated four commercially available syphilis point-of-care devices in a head-to-head comparison using sera from laboratories in Australia.
