Is the Risk for Sexually Transmissible Infections (STI) Lower among Women with Exclusively Female Sexual Partners Compared with Women with Male Partners? A Retrospective Study Based on Attendees at a Norwegian STI Clinic from 2004 to 2014

Background:

The prevalence of and the risk for sexually transmissible infections (STIs) for women engaging in same-sex sexual behaviour was investigated among women attending an STI clinic.

Methods:

Data from electronic medical records were reviewed and logistic regression used to estimate the odds ratio (OR) of STIs. Women reporting life-time exclusively female partners (WSW) and women reporting female and male partners (WSWM) were compared with women reporting exclusively male partners (WSM). Outcomes included: Chlamydia trachomatis, Mycoplasma genitalium, Neisseria gonorrhoea, HIV and syphilis.

Results:

The study population comprised 103 564 women (WSW 641, WSWM 12 010 and WSM 90 913). Overall prevalence of STIs was 8%. Crude OR of STIs for WSW: 0.56 (95% CI 0.39-0.81), for WSWM: 0.99 (95% CI 0.92-1.06) compared with WSM. Multivariate analysis revealed an interaction effect between same-sex sexual behaviour and smoking. Among non-smokers; WSW adjusted OR was 0.41 (95% CI 0.21-0.80), WSWM adjusted OR was 0.91 (95% CI 0.81-1.02) compared with WSM. Among smokers; WSW adjusted OR was 1.03 (95% CI 0.63-1.67) for WSWM adjusted OR was 1.00 (CI 95% 0.93-1.13), compared with WSM.

Conclusion:

This study, including the largest cohort of women reporting life-time exclusively female partners in an STI study, shows that WSW generally are at lower risk for acquiring STIs than WSM. Smoking WSW, however, had the same risk for acquiring bacterial STIs as WSM and WSWM. Our study suggests that all WSW should receive the same encouragement to test for STIs as WSM.

Prevalence of Seven Sexually Transmitted Organisms by Multiplex Real-Time PCR in Fallopian Tube Specimens Collected from Saudi Women With & Without Ectopic Pregnancy

BACKGROUND:

Ectopic pregnancy (EP) is associated with maternal morbidity and occasionally mortality during the first trimester. A history of sexually transmitted infection (STI) and pelvic inflammatory disease have been implicated as major risk factors for EP. Our aim was to measure the prevalence of Chlamydia trachomatis (CT), Neisseria gonorrhoeae, Mycoplasma genitalium (MG), Ureaplasma parvum/urealyticum, Gardnerella vaginalis, Trichomonas vaginalis and herpes simplex virus (HSV)-1&2 in Fallopian tubes collected from EP and the results were compared with those obtained from total abdominal hysterectomy (TAH) and tubal ligation.

METHODS:

This was a prospective case-control study and tubal samples were collected from 135 Saudi women recruited from 3 centres in the Western region as follow: 84 EPs, 20 TAH and 31 tubal ligations. Multiplex TaqMan PCR was performed using an IVD CE kit for the simultaneous detection of candidate pathogens following DNA extraction.

RESULTS:

Infections were detected in 31.8 % of the 135 participants either as single (11.1 %) or co-infections (20.7 %) and the frequencies were significantly higher in EP (42.85 %) compared with control (13.72 %). The rates of CT (27.4 %; P = 0.001); MG (20.2 %; P = 0.009) and HSV-1/2 (21.4 %; P = 0.01) were significantly higher in EP. No significant difference between the study groups was observed for the other pathogens (P > 0.05). Binary logistic regression also showed that infection with ≥ 2 pathogens (OR 4.9; 95 % CI: 2.2 - 11.6; P = 0.006), CT (OR 3.07; 95 % CI: 1.3 - 12.3; P = 0.002), MG (OR 2.3; 95 % CI: 1.1 - 8.6; P = 0.03) and HSV-1/2 (OR 1.7; 95 % CI: 0.75 - 5.7; P = 0.004) were associated with a significantly higher risk of developing EP.

CONCLUSIONS:

STIs are frequent in the upper genital tract of Saudi women during the reproductive age and, CT, MG and HSV-1/2 were more prevalent in EP. The observed high rates of co-infection advocate the necessity of establishing national guidelines and/or screening program utilising multiplex PCR approach for the detection of common STIs among high risk groups in the kingdom. Further studies are needed to measure the adverse reproductive outcomes associated with STIs in Saudi Arabia.

Asymptomatic Anal Sexually Transmitted Infections in HIV-Positive Men Attending Anal Cancer Screening

BACKGROUND:

HIV-positive men who have sex with men (HIV+MSM) have an increased risk for anal dysplasia and for sexually transmitted infections (STIs).

OBJECTIVES:

We determined the positivity rate of Chlamydia trachomatis (CT), Neisseria gonorrhoea (NG), Mycoplasma genitalium (MG) and syphilis in HIV+MSM participating in an anal cancer screening (ACS)-program.

METHODS:

852 intraanal swabs were collected from 503 HIV+MSM between 2012 and 2014. Anal cytology and PCR-assays for human papillomavirus (HPV)-, CT-, NG- and MG-detection were performed. The syphilis status was determined serologically. Risk factors for STIs were explored by multiple logistic regression analysis.

RESULTS:

20.7% (104/503) of the patients had a STI other than HPV within the study period. CT was found in 10.9%, followed by NG (8.9%), and MG (4.2%). Early syphilis was detected in 4.6% and past syphilis in 44.5% of the HIV+MSM. 18 patients (3.6%) had more than one STI episode. 90.6% of the 127 STI cases were asymptomatic. Age, anal HPV infection, abnormal anal cytology, and previous syphilis were risk factors for STI.

CONCLUSIONS:

Anal STIs are frequent and mostly asymptomatic in HIV+MSM participating in ACS. STI-screening should be incorporated in ACS-programs for HIV+MSM. This article is protected by copyright. All rights reserved.

Pelvic Inflammatory Disease associated with Chlamydia Trachomatis But Not Mycoplasma Genitalium in New Zealand

There is a paucity of studies looking at associations between Mycoplasma genitalium and pelvic inflammatory disease (PID). The objectives of this study were to estimate the prevalence of M. genitalium in women attending a sexual health service in New Zealand and secondly to examine for an association of M. genitalium with PID. 

Women consecutively attending the service for a sexual health screen (Chlamydia trachomatis, Neisseria gonorrhoeae and Trichomonas vaginalis) were recruited to establish a baseline prevalence of M. genitalium. An extra cervical swab was taken for the detection of M. genitalium. Recruitment of additional women with a clinical diagnosis of PID continued until a sufficient sample size was obtained to examine the association of PID with M. genitalium. Women in the baseline sample without PID were used as the control group. 

The control group included 250 women, with M. genitalium diagnosed in 8.7% (95% CI 5.8-12.9%) and C. trachomatis in 9.9% (95% CI 6.8-14.2%). Ninety-one women were recruited with PID; M. genitalium was diagnosed in 9.9% (95% CI 5.3-17.7%) and C. trachomatis in 27.5% (95% CI 19.4-37.4%). Multivariate analysis using clinically relevant variables showed that a diagnosis of C. trachomatis (OR 2.44, 95% CI 1.24-4.81) but not M. genitalium (OR 0.91, 95% CI 0.38-2.20) was significantly associated with a PID diagnosis. 

M. genitalium was almost as commonly diagnosed as C. trachomatis in this population. C. trachomatis was the only infection that was significantly associated with PID.
