The Number of Interviews Needed to Yield New Syphilis and Human Immunodeficiency Virus Cases Among Partners of People Diagnosed With Syphilis, North Carolina, 2015

imageCompare syphilis investigation yield among patient groups using number needed to interview. Goal: To increase investigation efficiency. Study Design: Retrospective review of North Carolina 2015 syphilis investigations, using the number of cases needed to interview (NNTI) and the total number of cases and contacts needed to interview (TNTI) to compare yield of new syphilis and human immunodeficiency virus diagnoses between patient groups. Results: We reviewed 1646 early syphilis cases and 2181 contacts; these yielded 241 new syphilis cases (NNTI, 6.9; TNTI, 16.4) and 38 new human immunodeficiency virus cases (NNTI, 43). Interviews of women (prevalence difference [PD] = 6%, 95% confidence interval [CI], 12–16), patients <30 years old (PD = 5%, 95% CI, 1–8), and patients with titer >1:16 (PD = 5%, 95% CI, 1–9) yielded more new syphilis cases in our adjusted model; no other patient factors increased investigation yield. Conclusions: The NNTI and TNTI are useful measures of efficiency. Prioritizing early syphilis investigation by gender, rapid plasmin reagin titer, and age provides small increases in efficiency; no other factors increased efficiency. 08/01/2017 01:00 AM
 

Mycoplasma genitalium Macrolide and Fluoroquinolone Resistance: Prevalence and Risk Factors Among a 2013–2014 Cohort of Patients in Barcelona, Spain

imageBackground: Macrolide and fluoroquinolone resistance is alarmingly emerging in M. genitalium worldwide. This article provides the first estimates of the current prevalence of macrolide and fluoroquinolone resistance–mediating mutations in Barcelona, Spain, and identifies risk factors associated with the acquisition of these resistances. Methods: The study was conducted retrospectively with specimens submitted between February 2013 and March 2014 to the microbiology department of the Vall d'Hebron Hospital, Barcelona, where M. genitalium was detected using nucleic acid amplification methods. DNA sequencing of 23S ribosomal RNA gene and parC was performed in the Statens Serum Institut, Copenhagen, to detect genotypic macrolide and fluoroquinolone resistance markers, respectively. Results: Macrolide resistance–mediating mutations were detected in 35% (95% confidence interval, 24%-47%) of the M. genitalium–positive episodes, whereas 8% (95% confidence interval, 3%-17%) carried fluoroquinolone resistance mutations. Of them, three cases harbored multidrug resistance to both classes of antibiotics. Men who had sex with men (P = 0.002) and treatment with azithromycin within the previous 12 months (P = 0.006) were strongly associated with macrolide resistance. Conclusion: The widespread appearance of resistances, also in Spain, makes imperative the implementation of combined diagnostic-resistance detection assays for M. genitalium to facilitate the optimization of antibiotic treatment in the management of nongonococcal urethritis and potentially reduce the transmission of resistances. 08/01/2017 01:00 AM

Narrative Review: Sexually Transmitted Diseases and Homeless Youth—What Do We Know About Sexually Transmitted Disease Prevalence and Risk?

imageBackground: Homelessness affects an estimated 1.6 million US youth annually. Compared with housed youth, homeless youth are more likely to engage in high-risk behaviors, including inconsistent condom use, multiple sex partners, survival sex, and alcohol/drug use, putting them at increased sexually transmitted disease (STD) risk. However, there is no national estimate of STD prevalence among this population. Methods: We identified 10 peer-reviewed articles (9 unique studies) reporting STD prevalence among homeless US youth (2000–2015). Descriptive and qualitative analyses identified STD prevalence ranges and risk factors among youth. Results: Eight studies reported specific STD prevalence estimates, mainly chlamydia, gonorrhea, and syphilis. Overall STD prevalence among homeless youth ranged from 6% to 32%. STD rates for girls varied from 16.7% to 46%, and from 9% to 13.1% in boys. Most studies were conducted in the Western United States, with no studies from the Southeast or Northeast. Youths who experienced longer periods of homelessness were more likely to engage in high-risk sexual behaviors. Girls had lower rates of condom use and higher rates of STDs; boys were more likely to engage in anal and anonymous sex. Additionally, peer social networks contributed to protective effects on individual sexual risk behavior. Conclusions: Sexually transmitted disease prevalence estimates among homeless youth fluctuated greatly by study. Sexually transmitted disease risk behaviors are associated with unmet survival needs, length of homelessness, and influence of social networks. To promote sexual health and reduce STD rates, we need better estimates of STD prevalence, more geographic diversity of studies, and interventions addressing the behavioral associations identified in our review. 08/01/2017 01:00 AM
 

Motherhood and Risk for Human Immunodeficiency Virus/Sexually Transmitted Infections Among Female Sex Workers in the Mexico-US Border Region

imageBackground: Globally, female sex workers (FSWs) have been identified as a high-risk group for human immunodeficiency virus (HIV) and sexually transmitted infections (STIs). However, as women of reproductive age, FSWs also have children. Few studies have investigated if financial responsibilities associated with motherhood increase women’s vulnerability to HIV and STIs among FSWs. Methods: From March 2013 to March 2014, 603 FSWs aged ≥18 years were recruited from Tijuana and Ciudad Juarez (Mexico) to participate in a study assessing HIV/STI risk environments. Results: Findings from logistic regression models indicate that FSWs who reported motherhood were more likely to report (in the past 30 days): a higher client volume (>30 clients) (adjusted odds ratio [AOR], 1.91; 95% confidence interval [CI], 1.27–2.87) and always using alcohol right before or during sex with clients in the past 30 days (AOR, 1.77; 95% CI, 1.19–2.61). In contrast, they were more likely to report consistent condom use for vaginal or anal sex with clients (AOR, 1.68; 95% CI, 1.10–2.55), less likely to report using drugs right before or during sex with clients (AOR, 0.38; 95% CI, 0.26–0.56) and less likely to have tested positive for STIs at baseline (AOR, 0.63; 95% CI, 0.43–0.91). Conclusions: These results provide a glimpse of the complex relationship between motherhood and women who are sex workers. Understanding the convergence of motherhood and sex work and how this can influence a woman’s decision when engaging in sex work and affect her health is essential to designing effective programs addressing reduce risk for HIV and STIs among FSWs in this region and elsewhere. 08/01/2017 01:00 AM
 

Prevalence and Risk Factors for Rectal and Urethral Sexually Transmitted Infections From Self-Collected Samples Among Young Men Who Have Sex With Men Participating in the Keep It Up! 2.0 Randomized Controlled Trial

imageBackground: Despite recommendations that sexually active men who have sex with men be regularly tested for sexually transmitted infections (STIs) and that testing reflect anatomical sites of potential exposure, regular testing is not widely performed, especially for rectal STIs. As such, little is known about the prevalence of rectal and urethral STIs among young men who have sex with men (YMSM). Methods: The current study examined the prevalence and risk factors for rectal and urethral chlamydia and gonorrhea in a sample of 1113 YMSM ages 18 to 29 years (mean, 24.07 years). Before participating in a randomized controlled trial for an online human immunodeficiency virus prevention program (Keep It Up! 2.0), participants completed self-report measures and self-collected urine and rectal samples. Participants mailed samples to a laboratory for nucleic acid amplification testing. Viability of self-collected samples was examined as a potential method to increase STI screening for MSM without access to STI testing clinics. Results: Results indicated that 15.1% of participants tested positive for an STI, 13.0% for a rectal STI, 3.4% for a urethral STI, and 1.2% for both rectal and urethral STIs. Rectal chlamydia was significantly more common (8.8%) than rectal gonorrhea (5.0%). Rectal STIs were higher among black YMSM compared with white YMSM. Additionally, rectal STIs were positively associated with condomless receptive anal sex with casual partners. Conclusions: Findings call attention to the need for health care providers to test YMSM for rectal STIs. This study also demonstrates the viability of including self-collected samples for STI testing in an eHealth program. 08/01/2017 01:00 AM

imageAbstract: Urinary meatal swabs compared with urine showed higher infection rates for Mycoplasma genitalium (15.3% vs 12.6%, P = 0.035), Chlamydia trachomatis (11.3% vs 9.3%, P = 0.039), Neisseria gonorrhoeae (1.4% vs 1.1%, P = 1.00), Trichomonas vaginalis (8.0% vs 1.7%, P < 0.001), and high-risk human papillomavirus (5.9% vs 3.4%, P = 0.078) respectively. 08/01/2017 01:00 AM
 

A Case of Decreased Susceptibility to Ceftriaxone in Neisseria gonorrhoeae in the Absence of a Mosaic Penicillin-Binding Protein 2 (penA) Allele

imageAbstract: We report a case of Neisseria gonorrhoeae with a non-mosaic penA allele that exhibited decreased susceptibility to extended-spectrum cephalosporins, including a ceftriaxone minimum inhibitory concentration of 0.5 μg/mL. An analysis of resistance determinants suggested that the observed phenotype might have resulted from the combined effects of mutations in multiple genes. 08/01/2017 01:00 AM
