ABSTRACT

OBJECTIVE: To systematically review and appraise published data, to determine the prevalence of Mycoplasma genitalium (MG) in men who have sex with men (MSM) tested at each anatomical site, that is, at the urethra, rectum and/or pharynx. DESIGN: Systematic review and meta-analysis. DATA SOURCES: Ovid Medline, PubMed, Embase were searched for articles from 1st January 1981 (the year MG was first identified) to 1st June 2018. REVIEW METHODS: Studies were eligible for inclusion if they reported MG prevalence in MSM tested at the urethra, rectum and/or pharynx, in at least 50 MSM, using nucleic acid amplification testing. Data were extracted by anatomical site, symptom and HIV status. Summary estimates (95% CIs) were calculated using random-effects meta-analysis. Subgroup analyses were performed to assess heterogeneity between studies. RESULTS: Forty-six studies met inclusion criteria, with 34 reporting estimates of MG prevalence at the urethra (13 753 samples), 25 at the rectum (8629 samples) and 7 at the pharynx (1871 samples). MG prevalence was 5.0% (95% CI 3.5 to 6.8; I2=94.0) at the urethra; 6.2% (95% CI 4.6 to 8.1; I2=88.1) at the rectum and 1.0% (95% CI 0.0 to 5.1; I2=96.0) at the pharynx. The prevalence of MG was significantly higher at urethral and rectal sites in symptomatic versus asymptomatic MSM (7.1% vs 2.2%, p<0.001; and 16.1% vs 7.5%, p=0.039, respectively). MG prevalence at the urethra was significantly higher in HIV-positive compared with HIV-negative MSM (7.0% vs 3.4%, p=0.006). CONCLUSION: MG was common in MSM, particularly at urethral and rectal sites (5% to 6%). MG was more commonly detected in symptomatic men at both sites, and more common in HIV-positive men at the urethra. MG was uncommonly detected in the pharynx. Site-specific estimates are similar to those for chlamydia and will be helpful in informing testing practices in MSM. PROSPERO REGISTRATION NUMBER: CRD42017058326.

ABSTRACT

OBJECTIVES: There are limited data on the prevalence of Mycoplasma genitalium (Mgen) coinfection with rectal chlamydia (Chlamydia trachomatis (CT)) and rectal gonorrhoea (Neisseria gonorrhoeae (NG)) infections and few studies examining the prevalence of pharyngeal Mgen in men who have sex with men (MSM). Using transcription-mediated amplification assay, this study aimed to determine the proportion of rectal CT and rectal NG infections in MSM who are coinfected with rectal Mgen, and the proportion of MSM with Mgen detected in the pharynx in order to inform clinical practice. METHODS: This was a cross-sectional study conducted at Melbourne Sexual Health Centre in Australia. Consecutively collected rectal swabs from MSM that tested positive for CT (n=212) or NG (n=212), and consecutively collected pharyngeal samples (n=480) from MSM were tested for Mgen using the Aptima Mycoplasma genitalium Assay (Hologic, San Diego). Samples were linked to demographic data and symptom status. RESULTS: Rectal Mgen was codetected in 27 of 212 rectal CT (13%, 95% CI 9 to 18) and in 29 of 212 rectal NG (14%, 95% CI 9 to 19) samples, with no difference in the proportion positive for Mgen. MSM with rectal CT/Mgen coinfection had more sexual partners than those with rectal CT monoinfection (mean 6 vs 11, p=0.06). MSM with rectal NG/Mgen coinfection were more likely to be HIV-positive than those with rectal NG monoinfection (OR=2.96, 95% CI 1.21 to 7.26, p=0.023). MSM with rectal CT/Mgen coinfection were more likely to be using pre-exposure prophylaxis than MSM with rectal NG/Mgen coinfection (OR 0.25, 95% CI 0.10 to 0.65, p=0.002). Pharyngeal Mgen was uncommon and detected in 8 of 464 samples (2%, 95% CI 1% to 3%). Pharyngeal Mgen was associated with having a rectal STI (OR=10.61, 95% CI 2.30 to 48.87, p=0.002), and there was a borderline association with being HIV-positive (p=0.079). CONCLUSION: These data indicate one in seven MSM treated for rectal CT or rectal NG will have undiagnosed Mgen that is potentially exposed to azithromycin during treatment of these STIs. Rectal Mgen coinfection was associated with specific risk factors which may inform testing practices. Pharyngeal Mgen was uncommon.

ABSTRACT

INTRODUCTION: Men who have sex with men (MSM) living with HIV have a high risk of anal cancer, which is often detected at late stages, when morbidity and mortality are high. The objective of this study was to describe the feasibility and challenges to incorporating regular digital anorectal examination (DARE) into routine HIV care for MSM living with HIV, from the perspective of patients, physicians and the health service. METHODS: In 2014, we recruited 327 MSM living with HIV, aged 35 and above from one major sexual health centre (n = 187), two high HIV caseload general practices (n = 118) and one tertiary hospital (n = 22) in Melbourne, Australia. Men were followed up for two years and DARE was recommended at baseline, year 1 and year 2. Data were collected regarding patient and physician experience, and health service use. An ordered logit model was used to assess the relationship between sociodemographic factors and the number of DAREs performed. RESULTS: Mean age of men was 51 (SD ± 9) years, 69% were Australian born, 32% current smokers, and mean CD4 was 630 (SD ± 265) cells per mm3 , with no significant differences between clinical sites. Overall, 232 (71%) men received all three DAREs, 71 (22%) received two DAREs, and 24 (7%) had one DARE. Adverse outcomes were rarely reported: anal pain (1.2% of total DAREs), bleeding (0.8%) and not feeling in control of their body during the examination (1.6%). Of 862 DAREs performed, 33 (3.8%) examinations resulted in a referral to a colorectal surgeon. One Stage 1 anal cancer was detected. CONCLUSION: Incorporation of an early anal cancer detection programme into routine HIV clinical care for MSM living with HIV showed high patient acceptability, uncommon adverse outcomes and specialist referral patterns similar to other cancer screening programmes.

ABSTRACT

The objective of this study was to determine the incidence and predictors of Fanconi Syndrome (FS) in a cohort of patients taking tenofovir disoproxil fumarate (TDF). Clinical records and laboratory investigations from patients receiving TDF between 2002 and 2016 were extracted. FS was defined as normoglycaemic glycosuria and proteinuria and at least one other marker of renal dysfunction. Regression analysis was performed with time to development of FS and the following covariates: ritonavir co-administration, age, gender, co-morbidities (hypertension, hyperlipidaemia, diabetes, viral hepatitis), CD4 cell count nadir and baseline eGFR. One thousand and forty-four patients received TDF without ritonavir and 398 patients with ritonavir. Thirteen cases of FS were identified with a mean duration of exposure of 55 months. The incidence of FS was 1.09/1000PY (0.54-1.63) of TDF exposure (without ritonavir) and 5.50/1000PY (3.66-7.33) of TDF-ritonavir co-administration (p=0.0057). The adjusted hazards ratio for ritonavir co-administration was 4.71 (1.37-16.14, p=0.014). Known risk factors for chronic kidney disease were not associated with development of FS. Ritonavir co-administration, but not other factors, is associated with a greater risk of FS. FS developed late. Known risk factors for chronic kidney disease and length of treatment are not useful for identifying patients most at risk of developing FS in patients taking TDF.

ABSTRACT

Smartphone dating applications have become a primary source for men who have sex with men (MSM) to meet sexual partners. It has been found that MSM who used smartphone dating applications are at higher risk of gonorrhoea, but the reasons remain unknown. This study aimed to investigate whether MSM who met their partners via smartphone dating applications are more likely to engage in sexual practices such as rimming (oro-anal sex), and use of partner's saliva as a lubricant, that are associated with the risk of gonorrhoea. A cross-sectional study was conducted among 1672 MSM attending the Melbourne Sexual Health Centre, Australia, between 31 July 2014 and 30 June 2015. Multivariate logistic regression was conducted to examine the associations between sources of meeting partners and the two aforementioned sexual practices. MSM who used smartphone dating applications were 1.78 (95% CI: 1.38-2.28) times more likely to get rimmed, and 1.63 (95% CI: 1.27-2.09) times more likely to use partner's saliva as a lubricant during anal sex, compared to other sources, after adjusting for age and other sources for meeting partners. These practices are highly associated with gonorrhoea.

ABSTRACT

BACKGROUND: The aim of this study was to ascertain the clinical characteristics associated with herpes simplex virus (HSV) urethritis in men and to compare those with chlamydial urethritis. METHODS: We compared clinical and laboratory data from men diagnosed with polymerase chain reaction confirmed HSV urethritis with those of men with chlamydial urethritis presenting to Melbourne Sexual Health Centre between 2000 and 2015. RESULTS: Eighty HSV urethritis cases were identified: 55 (68%, 95% confidence interval, 58-78) were by HSV-1 and 25 (32%, 95% confidence interval, 22-42) by HSV-2. Compared with chlamydial urethritis, men with HSV urethritis were significantly more likely to report severe dysuria (20% vs 0%, P < 0.01) or constitutional symptoms (15% vs 0%, P < 0.01). Men with HSV urethritis were significantly more likely to have meatitis (62% vs 23%, P < 0.01), genital ulceration (37% vs 0%, P < 0.01), or inguinal lymphadenopathy (30% vs 0%, P < 0.01) but less likely to have urethral discharge (32% vs 69%, P < 0.01). There was no significant difference in the proportion of men who had raised (≥5) polymorphonuclear leukocytes per high-powered field between the two groups (P = 0.46). CONCLUSIONS: The clinical presentation of HSV urethritis in men may differ from those of chlamydial urethritis and guide testing for HSV in men presenting with non-gonococcal urethritis.

ABSTRACT

BACKGROUND: There has been a rapid decline in the number of young heterosexuals diagnosed with genital warts at outpatient sexual health services since the national human papillomavirus (HPV) vaccination program started in Australia in 2007. We assessed the impact of the vaccination program on the number of in-patient treatments for genital warts. METHODS: Data on in-patient treatments of genital warts in all private hospitals were extracted from the Medicare website. Medicare is the universal health insurance scheme of Australia. In the vaccine period (2007-2011) and pre-vaccine period (2000-2007) we calculated the percentage change in treatment numbers and trends in annual treatment rates in private hospitals. Australian population data were used to calculate rates. Summary rate ratios of average annual trends were determined. RESULTS: Between 2000 and 2011, 6,014 women and 936 men aged 15-44 years underwent in-patient treatment for genital warts in private hospitals. In 15-24 year old women, there was a significant decreasing trend in annual treatment rates of vulval/vaginal warts in the vaccine period (overall decrease of 85.3% in treatment numbers from 2007 to 2011) compared to no significant trend in the pre-vaccine period (summary rate ratio (SRR) = 0.33, p < 0.001). In 25-34 year old women, declining trends were seen in both vaccine and pre-vaccine periods (overall decrease of 33% vs. 24.3%), but the rate of change was greater in the vaccine period (SRR = 0.60, p < 0.001). In 35-44 year old women, there was no significant change in both periods (SRR = 0.91, p = 0.14). In 15-24 year old men, there was a significant decreasing trend in annual treatment rates of penile warts in the vaccine period (decrease of 70.6%) compared to an increasing trend in the pre-vaccine period (SRR = 0.76, p = 0.02). In 25-34 year old men there was a significant decreasing trend in the vaccine period compared to no change in the pre-vaccine period (SRR = 0.81, p = 0.04) and in 35-44 year old men there was no significant change in rates of penile warts both periods, but the rate of change was greater in the vaccine period (SRR = 0.70, p = 0.02). CONCLUSIONS: The marked decline in in-patient treatment of vulval/vaginal warts in the youngest women is probably attributable to the HPV vaccine program. The moderate decline in in-patient treatments for penile warts in men probably reflects herd immunity.

ABSTRACT

OBJECTIVE: High rates of syphilis have been reported among men who have sex with men (MSM) internationally. Guidelines recommend presumptive treatment of sexual contacts of individuals with syphilis at the point of care. The aim of this study was to determine the proportion who were infected with syphilis and the factors predictive of infection among men reporting contact with a man with syphilis. DESIGN: Contacts who were syphilis infected (cases) were compared with those who were uninfected (controls). SETTING: This study was conducted at the main public sexually transmitted diseases clinic in Victoria, Australia. PARTICIPANTS: One hundred and seventy-two MSM presenting as sexual contacts of men with syphilis at a sexual health service in Melbourne, Australia, between July 2007 and October 2011 were assessed for syphilis. OUTCOME MEASURES: Proportion of MSM who are infected with syphilis and factors associated with infection. RESULTS: Of the 172 men who presented reporting contact with syphilis, 26 (15%, 95% CI 10 to 20%) had syphilis. One man had primary syphilis, 4 had secondary syphilis, while the remaining 21 had early latent syphilis. Infection was associated with unprotected anal sex over the prior 3 months (adjusted OR 6.1, 95% CI 1.4 to 26.8). CONCLUSIONS: One in seven men presenting as contacts of syphilis had syphilis infection, most of whom were latently infected. Contacts reporting recent unprotected anal sex were more likely to have syphilis.
