The CT positive and negative percent agreement were 90.1% (95% CI 80.7%, 95.9%) and 99.2% (98.1%, 99.8%), respectively. The NG positive and negative percent agreement were 96.2% (95% CI 86.8%, 99.5%) and 99.8% (95% CI 99.0%, 100%), respectively. Pooled testing identified 4 CT and 1 NG infections that were negative at all anatomic sites by individual testing.

Three-site pooled CT and NG testing performs similarly to single anatomic site testing among tests providing a valid result. Future cost analyses should evaluate the cost effectiveness of pooled three-site testing to determine if such a strategy improves the feasibility and accessibility of molecular STI testing.

Chlamydial infection is associated with tubal factor infertility (TFI); however, assessment of prior chlamydial infection and TFI is imperfect. We previously evaluated a combination of serological assays for association with TFI. We now describe the chlamydial contribution to TFI using a newer Chlamydia trachomatis Pgp3 enhanced serological (Pgp3) assay.

In our case-control study of women 19-42 years old with hysterosalpingogram-diagnosed TFI (cases) and non-TFI (controls) in two U.S. infertility clinics, we assessed possible associations and effect modifiers between Pgp3 seropositivity and TFI using adjusted odds ratios (aOR) with 95% confidence intervals (CI) stratified by race. We then estimated the adjusted chlamydia population attributable fraction (aPAF) with 95% CI of TFI.

All black (n=107) and 618 of 620 non-black women had Pgp3 results. Pgp3 seropositivity was 25.9% (19.3-33.8%) for non-black cases, 15.2% (12.3-18.7%) for non-black controls, 66.0% (95% CI 51.7-77.8%) for black cases, and 71.7% (59.2-81.5%) for black controls. Among 476 non-black women without endometriosis (n=476), Pgp3 was associated with TFI (aOR 2.6 [1.5-4.4]), adjusting for clinic, age, and income; chlamydia TFI aPAF was 19.8% (95% CI 7.7-32.2%) in these women. Pgp3 positivity was not associated with TFI among non-black women with endometriosis nor among black women (regardless of endometriosis).

Among non-black infertile women without endometriosis in these clinics, 20% of TFI was attributed to chlamydia. Better biomarkers are needed to estimate chlamydia TFI PAF, especially in black women.

Human papillomavirus (HPV) is the most common sexually transmitted infection in the United States; men who have sex with men (MSM) have higher prevalence of infection and related disease compared with other men. We assessed whether differences in HPV acquisition exist among MSM according to their sexual positioning practices as well as self-reported receipt of HPV vaccination.

We enrolled young MSM and transgender women aged 18-26 years in Chicago, Illinois (N=666). Participants self-reported history of HPV vaccination, and submitted self-collected anal swab specimens for type-specific HPV detection using an L1-consensus PCR assay. Multivariable logistic regression analyses were used to assess relationships between sexual positioning practices and detection of any HPV or quadrivalent HPV vaccine (4vHPV) types by vaccination status, defined as self-reported receipt of ≥1 HPV vaccine dose versus none.

Among 666 participants, 400 (60.1%) had any anal HPV, and 146 (21.9%) had a 4vHPV type. Among vaccinated ated disease incidence among adult MSM and transgender women as vaccinated cohorts age.Oropharyngeal cancer (OPC) is currently the most frequent Human Papillomavirus (HPV)-related malignancy in high-income countries. Oral HPV16 infection is the cause of HPV-related OPC in more than 90% of cases and is primarily (90%) linked to oral sex. This systematic review and meta-analysis aimed at comparing the prevalence of oral vaccine-type HPV infection in individuals vaccinated with HPV vaccines and unvaccinated controls. Three databases (MEDLINE, ScienceDirect and the Cochrane Library), as well as other sources were searched by two independent reviewers. Controlled studies testing the efficacy or effectiveness of licensed HPV vaccines were included. The primary endpoint was multiple HPV infections in one individual with low-risk and high-risk types. Secondary endpoint was the number of oral HPV16 infections. selleckchem Six studies - two randomized controlled trials and 4 cross-sectional studies - with a total of 15240 participants were included in a meta-analysis, which showed that vaccinated individuals were 46% [Risk ratio 0.54, 95%CI(0.32, 0.91)] less likely to develop oral vaccine-type HPV infection (p=0.02). A second meta-analysis of four studies (one RCT and three cross-sectional studies) and 13.285 participants showed 80% [Risk ratio 0.20, 95%CI(0.09, 0.43)] less likelihood of oral HPV16 infection (p less then 0.0001). This study suggests that HPV vaccines can protect against oral vaccine-type HPV infection including high risk HPV16 infection, thus reducing the incidence of HPV-related OPC. Vaccination against HPV, especially in males, who are predominantly affected by HPV-related OPC, could result in the prevention of this disease.
No studies have evaluated the utility and risks of screening for M. genitalium in men who have sex (MSM) taking PrEP. We made use of a quasi-experimental design to evaluate the effect of screening for M. genitalium in a demonstration PrEP cohort with 3 monthly follow up.

We compared the proportion of PrEP participants with M. genitalium clearance, the duration of persistence, proportion with incident symptoms, the incidence of fluoroquinolone and macrolide resistance and the proportion of non-cleared infections with resistance associated mutations between two groups - those in whom the first episode of M. genitalium was treated and those in whom it was not treated.

M. genitalium was detected in 70 out of 179 individuals. The first episode of infection was treated in 46 individuals. Treatment was not significantly associated with the incidence of symptomatic infections or the acquisition of genotypic resistance. Treatment was associated with a higher probability of clearance of infection but at the expense of increasing the proportion of remaining infections that were resistant.
