Asymptomatic and symptomatic urethral gonorrhoea in men who have sex with men attending a sexual health service.

OBJECTIVES: Guidelines regarding whether men who have sex with men (MSM) without symptoms of urethritis should be screened for urethral gonorrhoea differ between countries. We examined the rate of asymptomatic urethral gonorrhoea in MSM using sensitive nucleic acid amplification testing. METHODS: This study was conducted on consecutive MSM attending the Melbourne Sexual Health Centre between July 2015 and May 2016 for sexually transmitted infections screening. Gonorrhoea testing with the Aptima Combo 2 (AC2) assay was performed on all urine specimens obtained from MSM, whether symptoms of urethritis were present or not. Men were classified as having: typical discharge if they reported symptoms suggesting purulent discharge; other symptoms if they reported other symptoms of urethritis; and no symptoms if they reported no urethral symptoms. RESULTS: During the study period, there were 7941 clinic visits by 5947 individual MSM with 7090 urine specimens obtained from 5497 individual MSM tested with the AC2 assay. Urethral gonorrhoea was detected in 242 urine specimens from 228 individual MSM. The majority (189/242, 78%, 95% CI 73-83) reported typical discharge, 27/242 (11%, 95% CI 8-16) reported other urethral symptoms, and 26/242 (11%, 95% CI 7-15) reported no symptoms on the day of presentation and testing. Among men with urethral gonorrhoea, the proportions with concurrent pharyngeal or rectal gonorrhoea were 32% (134/210) and 64% (74/235), respectively. The mean interval between last reported sexual contact and onset of typical urethral discharge, where present, was 3.9 days. CONCLUSION: The findings from our study lend support to guidelines that recommend screening asymptomatic MSM for urethral gonorrhoea.

Comparison of conventional testing to polymerase chain reaction in detection of Trichomonas vaginalis in indigenous women living in remote areas.

There are high rates of Trichomonas vaginalis in remote areas of Central Australia. Conventional tests for T. vaginalis have low sensitivity in this setting. Aims of the study were to estimate the prevalence of T. vaginalis, to assess the presence of clinical signs and symptoms, to compare a T. vaginalis polymerase chain reaction (PCR) test with conventional methods of diagnosis, and to compare the PCR from different samples, including self-collected swabs (SCS). Of 205 women recruited, the prevalence of T. vaginalis was 24%. The prevalence of T. vaginalis was higher in women under 25 years (33%), compared with those who were 25-34 years (26%) and those over 35 years (15%, P < 0.05). The sensitivity of T. vaginalis PCR detection from SCS (94%) was not statistically different from a practitioner-collected HVS (96%), but was superior to urine PCR (74%) and conventional methods. After multivariate analysis, those women with high pH were almost three times more likely to be positive for T. vaginalis (odds ratio = 2.71 with 95% confidence interval 1.06-6.93, P = 0.037). Superior assays such as PCR should be a diagnostic option to adequately screen and treat women with T. vaginalis, in order to reduce complications, including the increased risk of HIV transmission.

Opting off the New South Wales Pap Test Register in a sexual health setting.

OBJECTIVES: To determine the proportion of women having a Pap smear at Sydney Sexual Health Centre (SSHC) who opted off the NSW Pap Test Register (PTR) and to establish the characteristics of these women. DESIGN: Retrospective cross sectional study involving three time periods during 1996 and 1997. SETTING: A public sexual health centre in Sydney. PARTICIPANTS: 985 women who had a Pap smear at SSHC. MAIN OUTCOME MEASURES: The participant's decision to opt on or off, and the demographic and behavioural characteristics associated with opting off the PTR. RESULTS: 590 (59.9%) women opted off the PTR. Using logistic regression, young age (p=0.005), birth outside Australia and New Zealand (p=0.0001), not speaking English at home (p=0.005) and being a commercial sex worker (CSW) (p=0.0001) were variables associated with opting off the PTR. Women from countries outside of Australia and New Zealand were more likely to opt off, whether or not they were a CSW and CSWs were more likely to opt off the PTR irrespective of their country of birth (p=0.013). CONCLUSION: The majority of women (60%) attending the SSHC opted off the PTR. Studies to evaluate culturally appropriate health promotion material particularly for CSWs and women with poor English skills living in Australia are needed and if successful may improve uptake on the PTR.

Management of women with recurrent genital herpes in pregnancy in Australia.

OBJECTIVE: To document clinical practice for the management of recurrent genital herpes in pregnant women in Australia. DESIGN AND PARTICIPANTS: A questionnaire to all doctors associated with the Royal Australian College of Obstetricians and Gynaecologists. MAIN OUTCOME MEASURES: Policies for antenatal herpes screening, circumstances in which delivery by caesarean section was considered appropriate, and the use of aciclovir during pregnancy. The results were analysed by college status, sex, and whether the doctor worked in a public or private facility. RESULTS: 2855 (67.3%) obstetricians returned questionnaires. 696 (34.3%) stated that their hospital had a policy for managing recurrent genital herpes in pregnancy: 44.5% examined the genitalia and 33.8% took cultures during pregnancy. Fellows were more likely to examine the genitalia (87% v 37%, p < 0.001), and more likely to perform antenatal viral cultures than members (75% v 30%, p < 0.001). Doctors working at private hospitals were significantly more likely to take viral cultures than doctors in public hospitals (39% v 33% p < 0.05). Doctors were asked to consider five scenarios and judge whether caesarean section would be appropriate. 96% considered that a caesarean section was appropriate in women with active herpes at the onset of labour. In the case of a recurrence of genital HSV at the time of presentation with ruptured membranes longer than 4 hours, diplomats (79%) were significantly more likely to recommend a caesarean section than fellows (64%), members (63%), or trainees (49%) (all p < or = 0.001). Where there were positive viral cultures before the onset of labour fellows (45%) were more likely than members (29%) (p = 0.005), males (62%) were more likely than females (55%) (p = 0.03), and doctors working in private hospitals (69%) were more likely than those in the public sector (54%) (p < 0.001) to recommend caesarean section. CONCLUSION: There is considerable divergence of opinion regarding the appropriate management of recurrent genital herpes in pregnancy. The implementation of management guidelines would provide consistency of care.

Sexually transmitted infections and risk behaviours in women who have sex with women.

OBJECTIVES: To assess the prevalence of sexually transmitted infections (STIs) and blood borne viruses, risk behaviours, and demographics in women who have sex with women (WSW). METHODS: Retrospective cross sectional study using a multivariate model. Demographic, behavioural, and morbidity data were analysed from standardised medical records of patients attending a public STI and HIV service in Sydney between March 1991 and December 1998. All women with any history of sex with a woman were compared with women who denied ever having sex with another woman (controls). RESULTS: 1408 WSW and 1423 controls were included in the study. Bacterial vaginosis (BV) was significantly more common among WSW (OR 1.7, p < 0.001). Abnormalities on cervical cytology were equally prevalent in both groups, except for the higher cytological BV detection rate in WSW (OR 5.3, p = 0.003). Genital herpes and genital warts were common in both groups, although warts were significantly less common in WSW (OR 0.7, p = 0.001). Prevalence of gonorrhoea and chlamydia were low and there were no differences between the groups. The prevalence of hepatitis C was significantly greater in WSW (OR 7.7, p < 0.001), consistent with the more frequent history of injecting drug use in this group (OR 8.0, p < 0.001). WSW were more likely to report previous sexual contact with a homo/bisexual man (OR 3.4, p < 0.001), or with an injecting drug user (OR 4.2, p < 0.001). Only 7% of the WSW reported never having had sexual contact with a male. CONCLUSION: We demonstrated a higher prevalence of BV, hepatitis C, and HIV risk behaviours in WSW compared with controls. A similar prevalence of cervical cytology abnormalities was found in both groups. Measures are required to improve our understanding of STI/HIV transmission dynamics in WSW, to facilitate better health service provision and targeted education initiatives.
